Unlike the cranial epidural space, the spinal epidural space contains adipose tissue, the internal vertebral venous plexuses and the spinal nerve roots. [1] The spinal epidural space spans the length of the spinal cord, from the foramen magnum superiorly to the sacral hiatus inferiorly. [6] Epidural space is the smallest at the cervical region ...

The internal vertebral venous plexuses (intraspinal veins) lie within the vertebral canal in the epidural space, [1] [2] embedded within epidural fat. [2] [3] They receive tributaries from bones, red bone marrow, and spinal cord. They are arranged into four interconnected, vertically oriented vessels - two situated anteriorly, and two ...
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
For epidural anesthesia an anesthetic agent is injected into the space just outside the thecal sac and diffuses through the dura to the nerve roots where they exit the thecal sac. [4] [5] For spinal anaesthesia in general, an injection can be given intrathecally into the subarachnoid space, or into the spinal canal.
The College Football Playoff got underway Friday but the main course is spread out through Saturday. Three first-round games will be played across three separate campus sites from State College ...
The epidural venous plexus is a venous plexus embedded within the epidural fat of the vertebral canal. [1] It is situated within the anterior epidural space (the outermost part of the spinal canal). The plexus extends from the skull base to the sacrum. It is surrounded by sparse fat (although its levels increase inferiorly).
